ath10k: enable rx duration report default for wmi tlv
When run command "iw dev wlan0 station dump", the rx duration is 0.
When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of
statsis not set by default, so firmware do not report rx duration.
one sample:
localhost # iw wlan0 station dump
Station c4:04:15:5d:97:22 (on wlan0)
inactive time: 48 ms
rx bytes: 21670
rx packets: 147
tx bytes: 11529
tx packets: 100
tx retries: 88
tx failed: 36
beacon loss: 1
beacon rx: 31
rx drop misc: 47
signal: -72 [-74, -75] dBm
signal avg: -71 [-74, -75] dBm
beacon signal avg: -71 dBm
tx bitrate: 54.0 MBit/s MCS 3 40MHz
rx bitrate: 1.0 MBit/s
rx duration: 0 us
This patch enable firmware's extened flag of stats by setting flag
WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in
ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID.
After apply this patch, rx duration show value with the command:
Station c4:04:15:5d:97:22 (on wlan0)
inactive time: 883 ms
rx bytes: 44289
rx packets: 265
tx bytes: 10838
tx packets: 93
tx retries: 899
tx failed: 103
beacon loss: 0
beacon rx: 78
rx drop misc: 46
signal: -71 [-74, -76] dBm
signal avg: -70 [-74, -76] dBm
beacon signal avg: -70 dBm
tx bitrate: 54.0 MBit/s MCS 3 40MHz
rx bitrate: 1.0 MBit/s
rx duration: 358004 us
This patch do not have side effect for all chips, because function
ath10k_debug_fw_stats_request is already exported to debugfs
"fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition
checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.
